如果需要设置两台机器的端口，请查看博文 centos7开放端口和防火墙设置

需要实现两台机器的信息交互，使用 socket 进行调度。其中服务端为：

#!/usr/bin/env python

# -*- coding: utf-8 -*-

import socket

# 服务端ip

server_address = ('192.168.229.129',10000)

# 客户端ip

client_address = ("192.168.229.130",10000)

s = socket.socket(socket.AF_INET,socket.SOCK_DGRAM)

s.bind(server_address)

while 1:

    data,addr=s.recvfrom(2048)

    if not data:

        break

    print("got data from",addr)

    print(data.decode())

    replydata = input("reply:")

    s.sendto(replydata.encode("utf-8"),client_address)

s.close()

客户端为：

#!/usr/bin/env python

# -*- coding: utf-8 -*-

import socket

# 服务端ip

server_address = ('192.168.229.129',10000)

# 客户端ip

client_address = ("192.168.229.130",10000)

s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)

s.bind(client_address)

while 1:

    data = input("input:")

    if not data:

        break

    s.sendto(data.encode("utf-8"), server_address)

    recivedata, addrg = s.recvfrom(2048)

    if recivedata:

        print("from:", addrg)

        print("got recive :", recivedata.decode())

s.close()

启动过后如下所示：

客户端发送：

input:hello world

from: ('192.168.229.129', 10000)

got recive : my name is server

input:my name is client,hahaha

from: ('192.168.229.129', 10000)

got recive : woca

服务端接收：

got data from ('192.168.229.130', 10000)

hello world

reply:my name is server

got data from ('192.168.229.130', 10000)

my name is client,hahaha

reply:woca
